Thread: Which driving lights should I buy for my dad? Off road use. Lightforce, Hella, etc?

There's something wrong there as there's only two openings, lens and bulb holder. Both have very decent oring seals on them. The lens is captive uunder the rim of the lens when it's bayonetted into place so would be hard to fail dur to being out of place. The globe holder oring could be nicked and let in water, especially if hot and dunked and so creates a vacuum.

High pressure cleaning can force water past the front seal.

They recommend not using a high pressure washer on the front.

They also improved the seal from an oring to a DE style U ring in recent months... This gives an even better seal.

Best thing is the reflectors are hard coated, so a simple wipe out and all will be perfect No dulling reflectors here!

So is the u ring a back up for the oring or a replacement for the original? Are they available as a part for upgrade?

water is one thing, but how the heck does dust get in?

It's a direct replacement, I sent an email to Fyrlyts and they got back to me within a few hours very professional in my view.

After a quick pleasant chat they sent me a new set FOC new U-rings to replace the old O-rings. Iv'e done over 10000 km with mine on the front and had no problems, I love my lights they are great .

How old are your Fyrlyts? Any idea when they started to fit the new u-rings? Thanks.

Mine are <6mth old and have the old style orings.

Relatively recent (last 2 months)...

Easy to tell... 2 x $0.05c pieces and spin the lens off...
See post directly above yours for what can be done if you have the older version!
